But this includes a non-masonry concrete foundation, leaving the stack's brick chimney at tall, only about taller than the monument's 2015 height. If the monument's aluminum apex is also discounted, then the stack's masonry portion is taller than the monument's masonry portion.

Located almost due east of the Reflecting Pool and the Lincoln Memorial, the monument, made of marble, granite, and bluestone gneiss, is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing tall according to the National Geodetic Survey (measured 2013–14) or tall according to the National Park Service (measured 1884).

The pyramid roof is an important feature of the building, enclosing a maintenance plant and housing facilities for water supply and window washing, and an aircraft warning beacon. The pyramid itself is 40 metres high and 30 metres square at the base. It is made from stainless steel and is held together by 100,000 nuts and bolts, with a weight of over 100 tons.

They built a small railroad to haul the heavy materials from the mountainside to the construction site. The work force grew to 35 men and the monument was completed by late winter with a surrounding iron railing. The Pennsylvania General Assembly of 1911 accepted the monument from the trust of Harriet Lane Johnston and Buchanan's Birthplace State Park was formally established.

For thousands of years, the Great Pyramid in Egypt was the tallest ""structure"" in the world, but the Great Pyramid is not considered a building since it is not habitable. The earliest structures now known to be the tallest in the world were the Egyptian pyramids, with the Great Pyramid of Giza, at an original height of , being the tallest man-made structure in the world for over 3,800 years, until the construction of Lincoln Cathedral in 1300. From then until the completion of the Washington Monument (capped in 1884)"

Typical for pyramids of the Middle Kingdom, the Black Pyramid, although encased in limestone, is made of mud brick and clay instead of stone. The ground-level structures consist of the entrance opening into the courtyard and mortuary temple, surrounded by walls. There are two sets of walls; between them, there are ten shaft tombs, which are a type of burial structure formed from graves built into natural rock.

"Pyramidion A pyramidion (plural: pyramidia) is the uppermost piece or capstone of an Egyptian pyramid or obelisk, in archaeological parlance. Speakers of the Ancient Egyptian language referred to pyramidia as ""benbenet"" and associated the pyramid as a whole with the sacred benben stone. During Egypt's Old Kingdom, pyramidia were generally made of diorite, granite, or fine limestone, then covered in gold or electrum; during the Middle Kingdom and through the end of the pyramid-building era, they were built from granite. A pyramidion was ""covered in gold leaf to reflect the rays of the sun""; during Egypt's Middle Kingdom pyramidia were"

Their goal is to expand on Petrie's work by re-gathering architectural details of the monuments there, which Petrie had neglected to record in his reports. The core of the pyramid was constructed from mudbrick around a stump of four steps of yellow limestone. The builders utilized a rock outcropping to anchor the pyramid and reduce construction time and cost. The completed pyramid was originally encased in white limestone, though an inscription found by Petrie indicates that the casing was"

Because Frishmuth had previously done plating work for the Washington Monument, in 1884 the Army Corps of Engineers asked Frishmuth to construct a small metal form for the top of the monument. The small pyramid was to be artistic, and function as the terminus of a lightning rod. Frishmuth suggested aluminum, as its color would blend well with the granite, would not stain, would polish well, and could be engraved with inscriptions. In 1884 he cast the"

It consists of nine stories with talud only, covered in stucco. Each story above is smaller than below, leaving a space of two meters. The entrance stairs were those on the southeast corner, with those on the other three serving as exits. These walls were painted black with the stucco serving as white. Associated with the Stepped Pyramid is the Jaguar Altar, which is located on the southeast corner. The west and"

For the actual pyramid, unhewn granite blocks were used and particularly hard loam mortar was used to hold them together. No chamber system exists. On the north side of the structure is a cut near the middle, which was made by the 1909 French excavation team led by Henri Gauthier.

The eight sections formed by these walls were then subdivided by three more walls, splitting the pyramid into 32 different units which were then filled with slabs of stone as well as debris. An exoskeleton of fine limestone then covered the structure.[1] This new method of construction was not particularly efficient, however, and the completed pyramid suffered from stability problems. Unusually, clear evidence for the ramps used to construct the pyramid also remain. Surrounding the actual structure was a comparatively large complex, which consisted of a mortuary"

It is now about 4.9 metres high. It consisted of a core structure measuring 8.3 metres on each side, surrounded by two courses of stone about four cubits thick. Dreyer and Kaiser suggested that the pyramid had had three steps. The angle of the slope cannot be accurately determined, but it was probably between 10° and 14°.

It is constructed entirely out of concrete made with Portland cement, with only the windows having iron supports. It remains the tallest non-reinforced concrete structure in the world. It was originally designed as a mausoleum, with a perpetual light at the top. However this was not allowed by Trinity House, as it was thought the light would confuse shipping. It also served to publicise the superiority of Portland cement; even then not fully accepted."

Yale tour guides frequently mention the legend that the tower was the world's tallest free-standing stone structure until it required reinforcement after an eccentric architect or philanthropist ordered acid to be poured down the walls to make it look older. In reality, the Washington Monument was the country's tallest such structure long before Harkness Tower was built. The towers's decorative elements were sculpted by Lee Lawrie. The lowest level of sculpture depicts Yale's ""Eight Worthies"": Elihu Yale,"

Construction of the monument began in 1848, and was halted from 1854 to 1877 due to a lack of funds, a struggle for control over the Washington National Monument Society, and the intervention of the American Civil War.
